propzapi-skills
Agent skills for template-based image generation and webpage screenshots. Drop-in skills that let any agent render an image from an HTML/CSS template, snapshot any live URL, and manage a template library — over the propzapi REST API.
Templates are HTML/CSS with {{variables}} and Jinja logic ({% if %}, {% for %}, filters). Fill the variables with one JSON call and get back a rendered PNG/JPEG/WEBP/PDF at a stable URL — no headless browser to run, no fonts to install. Perfect for Open Graph images, social cards, certificates, invoices, receipts, and data charts.
Free to start — grab a key (50-image trial, no card required) and you're rendering from Claude, Cursor, Cline, or your own agent loop in under two minutes.
Pure Python standard library. No dependencies. MIT-0 licensed.

Authentication
Set the PROPZAPI_KEY environment variable to your propzapi key. It's sent as the X-API-Key header — the base URL is hardcoded, so the key never reaches any other host.
export PROPZAPI_KEY="your_key"Get a free key — 50-image trial, no card required. You can also mint one with POST /v1/register → {api_key, plan, credits}. The same key works for these skills and direct REST calls.
Pricing
Each rendered image or screenshot costs 1 credit — the response returns the exact charge in the X-Credits-Cost header, and your balance in X-Credits-Remaining. Listing and creating templates is free.

| Free trial | $0 | 50 |
| Starter | $29/mo | 1,000 |
